How to make time slots without the need for real time (it is just simulation)

Question

now i am making a simulation for something and i need to define time slots for it as i can not use the real time . For example , i want to know how many persons entered the bank in the 1st 5 minutes and then in the second 5 mins and so on , i want to simulate only so i do not wait 5 miin every time to be able to take the results.

can anyone help??

You keep a priority queue of future events sorted by arrival time. Then just take the first and handle it until there is no more event remaining.

Thanks alot for reply in advance :-) but all what i want to is to calcualte for example the number of persons came in the first slot. in the code i don not know when these persons arrive . also i want to insert to it a definition for the timeslot to be able to calculate the delay for one person. do you understand what i am trying to do or you need more explanation :-) ?? – fank Apr 15 '11 at 13:55

Don't know if this is what you are looking for, but it sounds like Discrete Event Simulation could help.

It seems like you need two things.

To maintain a record of how many arrivals occurred by timeslot. This is called a histogram. The timeslot ( usually called a bin when discussing histograms in general ) of each arrival is calculated ( integer division is often useful here ) and the correct bin count ( array or vector ) is incremented.
To estimate the delay experienced by each arrival. This requires discrete event simulation - a big subject. The Wikipedia article is probably a good start.

thanks for reply i worked before with the discrete time event simulation but sorry i can not understand well how i can implement the 1st thing concerning the histograms. can you explain more or give me a website or anything to understand more?? :-) the question is : can i use these histograms and timeslots without using real time? thanks alot – fank Apr 18 '11 at 08:35
